Checking fuel pressure with tire pressure gauge?

Hello, is it possible to check my fuel pressure with a basic PSI gauge? Or would that just give me a reading while spraying gas all in my engine bay?

Haha

I mean....give it a try?

pretty sure autozone rents a fuel pressure tester for free????

I understand it will work, use some towels to make sure you do not get too much spray.

Suggest you try initially without the engine running so you can get an idea how messy/dangerous it may get.

Proper fuel pressure gauge is the best approach in the end anyway.

How/Did it work? Just curious.

Hrm. Even doing it with the engine off might be sketchy (fuel lines stay pressurized all the time I think).

I'm not COMPLETELY broke.. so no reason not to do it right.

Going to try and rule out other things for my rough idle first though. (Re-inspect DISA, elbows, ICV)

Fuel pump/pressure rarely causes rough idle, it causes other problems, but usually not at idle.

Suggest you read the first link below in my signature.

Give it a go and let us know what happens. Make sure you video it. We have a TV show in the UK called You Been Framed. They'll give you £250 for it.
